. l IMPROVEMEN'I'IN' HORSE-RAKES.

1 The chedule referred to in these Letters Patent and making part 0f the same- Be it known that I, PARKER A. 'THAYErn of The- `have invented certain new and useful Improvements in ItevolvingHorse Hay-Rakes; 4and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw-- ings, making part of this speciiication, and to the letlike parts wherever they occur.

To enable others skilled inthe art to-construct and use my invention, I will proceed to describe it.

, My invention relates to revolving horse hay-raises, and consists in the construction and arrangement of gle or position of the teeth of the rake, and allowing In the drawingslligure 1 is a side or end view,- and Figure 2 isa top plan view.

In constructing my rake, I make a frame, A, conc, the latter forming the shafts for attaching the horse, iidesired, and oi' any size desired, and out of any suit To the lower ends of the nprights c, I attach a rake, B, by metal straps or loops, el, or other suitable devices, and in such a way as to allow the rake 'to turn easily in its connections, and to the rear side of the and staple, or by any other device desired, the handles C, all as clearly shown in both iigures.

These handlesO, I provide, near their centres, with a cross-bar, e, and neartheirends, with connecting-rod T o the cross-piecec, of thefranie A, and near its passing through a slottedjron, It, hinged-to the pitinanD, as clearly shown in fig. 2. v

'lhe opposite end ofthe pitman D, I hinge or connect loosely to a suspended brace', Il,.andv at` a4 short distance below its point or points 'of suspension, as shown in figs. l and 2.

'.lhis brace F, I makesuiiiciently broad tobear against twoloi more of the teeth ofthe rakeat the same time, and suspend it from the cross-piece c by means ofniet- `allie loops passing about a rod bolted or fastenedl to 'lo the outer sides of' the side pieces l), of the frame A, I connect loosely extension-rods G atone end, and

bolts '5, having iirst provided them with a screw-thread and screwed thereon the nut j. After they are passed through'theseeye-bolts, I place on another nut, 7c, as `shown in both ligures.

Tl'iese nuts t and ccan be readily adjusted at dif`erent distances apart, Vso as to allow the rods G to be shortened or lengthened, as desired, and also to have a longitudinal movement equal to the distance between the nuts. y

Also, to the outer sides of the side pieces b, I attach Vvertical steel springs, H, by means of a bolt passing through a slot in their upper ends. The lower' ends of these springs are bent at iight angles inwardly, and are so arranged as to bear against the upper sideof the teeth ofthe rake, as shown in iig. 1, and thus prevent the rake from turning only in one direction.

By this construction, it will be seen that the pitman i D and steel springs II may be conveniently lengthened or shortened by means of their slotted connections, as desired, and that the extension-rods G, at the sides, are not only susceptible of being lengthened or shortcned, but may also be given any desired play longitudinally, which function is essential tothe operation of my rake.

In 'operating it, I adjust the springs, pitman, and extension-rods, so as to give any angleor pitchithat may be deshed to the teeth, to suit the work to be done. To increase the pitch, the springs should be lengthened, and the lpitman and extension-rods shortcned, while the reverse of this is required to diminish it. At the same time I fix the distance between thc nuts j and 7c, so as to allow the handles C to be raised just far enough for the pitman l) to'throw'or swing the brace E clear of the teeth of the rake as it revolves. When'all the parts are properly adj usted, the rake is drawn along as `fiar as desired, then, by simply elevating the handles, the 'brace is thrown clear of the teeth, andthe rake is free to revolve and deposit its load. By dropping the handles, it is caught again between Vthe springs and the brace, andready for operation again, and so on till the work is completed.

Having thus described my invention, What I claim, is-

1. The combination of the frame A, rake B, and handles C with the springsH, pitman D, and extensionto b e adjustable, and operate1 in 'the manner substan# tially as described, and for thepurpose set forth.

2.l Providing the rods G with the nuts j and k, to adjust the length of the rods, and to regulate their longitudinal movement, substantially as herein described, andvfor the purpose set forth.P

3. lhe adjustable slotted iron h, when constructed and arranged as described, andfor'the purpose set
